createAnalysis

Multiple fragments with fractional stoichiometric coefficients are supported:
CH3O.0.5Na.1.5H2O, NaCl.1.5H2O, AlCl3.1.5H2O
If the molecular formula contains any unspecified symbol (e.g. R, Pol) the analysis do not take into
consideration these symbols. The analysis returns the same result for formulas either with or without these
symbols.
